Title: Improved Process of and Means for Acting upon Atmospheric Air or any Fluid for the Purpose of Recuperating therefrom a Contrary Reaction.
Inventor: LENTZ HUGO
Filed: 1906-06-18
Granted: 1907-06-18
Abstract: 13,959. Lentz, H., and Bellens, C. June 21, 1905, [date applied for under Patents Act, 1901]. Propelling.-Relates to means for propelling, lifting, or raising bodies by the action on the surrounding fluid of a rapidly reciprocating surface, in which the surface always moves parallel to its initial position and the outward or active movement of the surface is more rapid than the return movement. The rapid outward movement of the surface against the fluid causes the fluid to partake of the nature of a solid and to react on the moving surface. The invention is described as particularly applicable to raising aerial machines without the aid of aerostats, but may be used for any desired purpose, and any suitable motive power may be used to give the surface the reciprocating movement. The rapid outward movement followed by a comparatively slow return may be produced by a path k, Fig. 5, having tooth-like projections in which the upward part 1-2 is steeper than the downward part 2-3. Such a path may be mounted on the periphery of a plate r, Fig. 5, in contact with a roller h secured on the surface to be reciprocated. The plate r is geared to be rapidly rotated, and the roller h is kept in contact with the path k by a spring i. The surface, which is of any form, may be enclosed in a casing u. The Specification in the original form as published under the Act of 1901 stated that the invention was applicable also to terrestrial locomotion and to marine and submarine navigation. This statement does not appear in the Complete Specification as accepted.

Abstract: 18,779. Craven, P. P. Aug. 22. Reeling, traverse mechanism for. In crosswinding yarn, thread, or string into cops, bobbins, or cheeses having flat ends, the material is prevented from overwrapping the ends of the cop &c. by arranging that the traverse of the oscillating thread-guide is gradually shortened as the package is being built up. The thread-guide A is mounted on a shaft B, rocked by a slotted lever C, which is operated by another slotted lever D mounted on a shaft U at the front of the machine. The lever D is rocked by a cam F and is connected to the lever C by a sliding-piece K which is normally pulled by a weight S towards the end of the slots giving the maximum throw of the lever C. A chain P, which is slowly wound-up on a shaft W, is also connected to the sliding piece K and moves it so as to gradually diminish the throw of the lever C, and hence of the thread-guide A, as the winding proceeds. In a modified arrangement, the lever D is mounted at the back of the machine near the shaft B. Specifications Nos. 22,932 and 27,099, A.D. 1904, [Abridgment Class Spinning], are referred to.

Abstract: 23,864. Lake, H. H., [Chemische Fabrik Griesheim-Elektron]. Oct. 26. Dyes, artificial.-Indophenols are obtained by the oxidation of alpha-naphthylarylsulphamides with p-aminophenol or its derivatives ; these indophenols, or their leuco derivatives, are converted ioto sulphur dyes by heating with alkali polysulphides. In an example, p-aminophenol is dissolved in caustic soda solution, and alpha-naphthylp-tolylsulphamide is dissolved in caustic soda solution ; the solutions are mixed and sodium hypochlorite solution is added, the whole being cooled by ice ; the indophenol separates out as a resinous mass. The leuco-derivative is prepared by adding sodium sulphide solution to the mixture containing the indophenol and heating ; from the filtered solution, the leuco body is precipitated by a mineral acid. An alkaline solution of the leuco body rapidly oxidizes giving a bluish violet colour; an alcoholic alkaline solution gives a pure blue. The indophenol, or leuco body prepared as above, is melted with sodium sulphide and sulphur with a small amount of copper or copper sulphate ; the product is diluted with water, heated, and filtered ; the dye is precipitated by a current of air and when dry is a black-green powder, dissolving in strong sulphuric acid and to a blue solution, and in alkali sulphides to a green solution. It dyes cotton fast green tints. the chlor-derivative of the aminophenol, or the alpha-naphthylbenzenesulphamide, may be used in the above process.

Granted: 1908-03-19
Abstract: 7233. Robertson, D. March 26. Elastic-fluidturbines.-The vane rings of elasticfluid turbines are divided into concentric sections, which may be caused to operate either separately or collectively, whereby the power of the turbine may be varied. In the turbine shown in Figs. 1 and 2, three parallel-flow expansion stages are used. The method of dividing the vanes is shown in Fig. 2, in which three rings are secured to the vanes so as to divide them into four sections a<3x> ... a<3xxxx> All the vanes and guideblades throughout the turbine are similarly divided. Steam is admitted through a pipe d<1> and after passing a piston valve d<2>, controlled by a handwheel d<3> or by a governor, enters one or more of the passages e' ... e<4> in a casting e, after which it acts upon one or more of the concentric rings of blades in the high-pressure stage a<1>. Then:e it exhausts into four passages in a casting f and passes into the intermediate pressure stage a<2>; it then passes through channels in a casting g to the low-pressure stage a<3>. The steam is finally exhausted into four passages h<1> ... h<4>, whence it passes through valves h<1x> ... h<4x>, controlled by separate hand-levers, to the exhaust pipe h<x>. When the inlet valve is in the position shown in Fig. 1, steam is entirely cut off. As it is moved to the left, it admits steam first to the outer sections of the vanes and then to the other sections successively. One or more of the sections may thus be rendered inoperative, and the similar sections throughout the turbine are consequently rendered inoperative also. Whenever any section is cut out, the corresponding valve at the exhaust is closed. By this method of varying the effective vane area for varying loads, the correct pressures throughout the turbine are maintained. The invention may be applied to any type of parallel or radial flow turbine.

Abstract: 7697. Fletcher, H. O. March 29, 1906, [date applied for under Patents Act, 1901]. Variable-speed gearing ; mounting toothed wheels on shafts. - Relates to means for preventing shock when toothed wheels are slid into mesh while in motion. Wheels 9, 10 upon a shaft 3 are driven from wheels 4, 5 of different sizes fast upon a shaft 2. The wheels 9, 10 are formed as nuts screwing upon spiral threads 11 upon sleeves 6, 7, respectively, which slide upon feathers &c. on the shaft 3. The gears 9, 10 have lugs 16 adapted to strike buffers 19 upon shoulders 17 formed on raised bosses 14 upon the sleeves 6, 7, so that the gears drive the sleeves positively after the threads 11 have been passed over. The gears are normally thrust to the left out of mesh by springs 12. When engagement is to be effected, a rock-shaft 23 is turned so that one of two arms 21, 22, Fig. 2, engages a groove 20 in one of the sleeves 6, 7, and the shaft 20 is thrust to the right carrying the selected sleeve with it. When the movable gear involved begins to mesh with the corresponding driving-gear, it rapidly screws forward and is in full mesh before the positive drive sets in. When the arm 21 &c. is turned out of engagement, the sleeve 6 &c. in operation is thrust to the left by a spring 27, and the gear 9 &c. on coming out of mesh is thrust farther to the left by its spring 12.

Title: Improvements in Direct Current Armatures with Multiple Circuit Multiple Winding.
Inventor: PUNGA FRANKLIN
Filed: 1907-05-09
Granted: 1908-02-13
Abstract: 10,861. Punga, F. May 9. Armatures; sparking, preventing. - In a directcurrent armature with a multiplex winding, equalizing-connexions are provided between the different individual windings so that the potential of each commutator segment is substantially midway between the potentials of the two neighbouring segments, thereby improving the commutation. In Fig. 1, the armature is shown provided with two windings I, II connected to alternate commutator segments. Equipotential points on the winding I are jointed to equalizing-rings m, and equipotential points on the winding II to equalizing- rings n. The rings m, n are in turn connected by leads o in such a manner that neighbouring conductors of the two windings are short-circuited by these leads. The number of equalizing-rings may be a fraction of the number of commutator segments per pole, or the rings on the side remote from the commutator may be entirely omitted, the conductors of the second winding being connected through the armature with the equalizing- rings of the first winding. The method of counexion is applicable to quadruplex and sextuplex windings. In a modification, shown in Fig. 2, applied to a doubly-wound four-pole machine, commutator segments corresponding to different windings are connected in pairs by equalizing- leads r, and similar points on the windings on the side remote from the commutator are connected by leads s. The leads r, s are then joined by conductors t as in the previous example. This arrangement is applicable to multiplex windings by connecting together a suitable number of commutator segments symmetrically situated around the commutator. With high-speed direct-current machines, the armatures may be made in two parts or with a large duct in the middle so that a set of equalizing-connexions can be joined to the middle points of the windings. In all cases, the windings are distributed in the slots in such a manner that the electromotive forces induced in the circuit between two neighbouring equalizing- connexions are eliminated.

Title: Improvements in Coking, or Distilling, Coal for the Manufacture of Coke and Production of Gas
Inventor: SHELDON SAMUEL BERTRAM
Filed: 1907-10-02
Granted: 1908-02-06
Abstract: 21,808. Sheldon, S. B. Oct. 2, 1906, [date applied for under Patents Act, 1901]. Coke ovens charging and discharging.-Coke is made in horizontal ovens by a practically continuous process, the gas produced being led off and treated in the usual way. Each oven is provided with a compressing, perforating, and charging device, and with a discharge duct arranged to prevent entry of air to the oven during working. Coal, preferably pulverized, is fed through a hopper 28 to a chamber 24 in which a piston 30 is reciprocated by suitable means, oppositely disposed hydraulic cylinders 34, 35 being shown. The coal is forced through a tapering passage 25 whereby compression of the charged is obtained. The piston 30 carries rods 50 round which the coal is compressed so that longitudinal perforations are formed, rendering the e coking more uniform and facilitating withdrawal of gaseous products. Succeeding supplies of coal force the compressed material through a pre-heating chamber 26 in which partial coking occurs, producing coherence between the particles of coal so that the charge retains its compressed and perforated form when it enters the oven. The chamber 26 is preferably of metal and heated by the combustion of gaseous fuel in a surrounding chamber 36, combustion products passing off through tubes 37. The coke is discharged through a duct 52 having two valves of suitable form to exclude air. The upper valve 53 is preferably an horizontally-sliding gate, and the lower valve 54 a counterbalanced cone, as shown. A water-cooled jacket 40 surrounds the chamber 36, and a water-cooled cap 45 projects into the oven just below the crown. Water-cooled rings 46, 57 are provided between the ends of the oven and the charging and discharging devices respectively. In a modification, the chambers 36,40 are extended to surround the chamber 24 and tapered passage 25, and the rods 50 pass through holes in the plunger 30 and are carried by a separate cross-head. The oven is preferably of the "Otto Hoffman" type. Two independent sets of heating-flues are provided so that the half of the oven next to the charging-device may be maintained at a temperature sufficiently high for coking, the other half being at a lower temperature so that partial cooling of the coke takes place before discharge. At the commencement of operations, an initial charge is introduced into the oven through an opening 62 in the crown. An exhauster (not shown) may be used to withdraw the distillation gases so that the coking is effected at a pressure not greater than that of the atmosphere.

Title: Improvements in the Manufacture of Photographic Colour Screen Plates
Inventor: PALMER HENRY WILLIAM HAMBLIN
Filed: 1907-10-09
Granted: 1908-10-09
Abstract: 22,228. Palmer, H. W. H. Oct. 9. Colour photography ; screens; sensitized plates &c. -Screens and plates for colour photography are prepared by first coating with a tacky substance such as gelatine, or a varnish, and coating over with very fine fluxes very intensely chemically stained with metallic oxides. The surface is levelled and rolled, and then varnished before coating with the emulsion if plates are required. Or, alternatively, the plates are covered evenly over with the ceramic colours or fluxes and fired so as to form a coloured transparent glaze as part of the surface, the process resulting in the filling up of any interspaces between the coloured particles. The coloured particles may be evenly distributed for the above purposes conveniently by means of a sand blast or air brush. The transparent support may be coloured slightly yellow to moderate the activity of the blue-violet rays, and thus avoid using a yellow filter. The screens are adaptable to celluloid films. For the colour coating, silica, minium, and borax, with the additions of saltpetre if required, are used with various colouring-ingredients, such as oxides of cobalt, chromium, copper, tin, or iron, or chromate of lead or of gold in the required quantities. For printing upon paper or other support, this may be done from photo - mechanical relief blocks made from the screen plates, or the various sets of colours printed in exact register may be coated with printing-art emulsion, and printed from the colour negatives and positives. The Provisional Specification also includes a description of the use of strands of spun glass, silk, or gelatine, for the plates, these being embedded in a tacky coating on the support, and also a machine for forming the screen. Further, the use is described of fine particles of spun glass either by coating or firing as above, or by flashing the colours into different patterns. The particles of spun glass may be cut with a microtome so as to be of equal and even size.
